TPS2052ADR

The TPS2052ADR from Texas Instruments is a high-side MOSFET power switch designed for robust power distribution systems. It is intended for applications where heavy capacitive loads and short circuits are likely to be encountered.

This device incorporates an 80-mΩ N-channel MOSFET high-side power switch. Each switch is controlled by an independent logic enable input. The charge pump internal to the device controls power-switch rise and fall times to minimize current surges during switching, allowing operation from supplies as low as 2.7 V. When the output load exceeds the current-limit threshold or a short is present, the device limits the output current to a safe level by switching into a constant-current mode.

Overload and short circuit conditions that increase power dissipation trigger a thermal protection circuit, shutting off the switch to prevent damage. Recovery from thermal shutdown is automatic once the device has cooled sufficiently. The TPS2052ADR operates within a supply voltage range of 2.7 V to 5.5 V and has a continuous current rating of 500 mA per channel. It features undervoltage lockout and independent thermal and short-circuit protection with an overcurrent logic output.

The TPS2052ADR is supplied in an 8-SOIC package. It operates over an ambient temperature range of 0°C to 85°C, with a junction temperature range of 0°C to 125°C. The device is suitable for applications requiring reliable power management and protection against fault conditions.
